Be it known that I, CHARLES A. TATUM, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Atomizers, of which the following is a specification.

My invention relates Ato that class of atomizers in which the atomizer proper-:when not in use may be placed within the bulb, so as to be protected thereb'y and to reducethe bulk of the apparatus. V A l The object of my present invention is to provide means forproducing an airtightjoint between the bulb and thevatomizer 'proper when the latter is in position for use and to prevent an accidental movement ofthe atomizer proper when it is within the bulb.-

The invention will be fully described hereinafter and the features of novelty pointed out in the appended claims.

Reference is to be had'to the accompanying drawings,which represent atypical form of my invention, and in which- Figure 1 is an elevation with parts in section, showing the atomizer in position for use. Fig. 2 is 'a similar view withftheA atomizer proper within the bulb, and Fig'. 3 is a plan of lthe device in the position shown in Fig. 2.

A is the bulb, which may be of any sui-table construction. A substantially cylindrical bulb is shown, with its air-' inlet'indieated at A'. At the outlet I arrange a sleeve or thimble B, made of hard rubber or other suitable material and provided with an internal screwthread B. A Washer C vis secured to the thimble, as by means of vwire c, and the lower portion of this washer projects inwardly and has an annular edge or bead C. This bead is adapted to engage the outer surface of the atomizer proper, D, VWherrlthe latter is within the bulb, as in Fig'r2, or the bottom-of the atomizer proper when the latter is in the projected position, Fi'g.1. p f

The construction of the latomizer proper may be Varied considerably, although I prefer to use an atomizer the bottom of which is inclined, as shown at D'. I have shown a central tube E, through the medium of which the air is blown from the bulb to the'atomizer proper, and a liquid-conveyin g tube F, which dips into the liquid contained in the atomizer and terminates adjacent to the outlet of the air-tube E. The outlet of the atomizer may' be closed by a stopperl G whenit is desired to invert the atomizeljas shown in Fig. 2.

The receptacle or body D of the atomizer proper is provided with a screw-thread D2, adapted to fit the-thread B' of the thimble B.

When in positionfor use, the atomizer proper 6o is screwed into the Athimble B, so as to project outwardlytherefrom, as shown in Fig. l, and the act of screwing in the atomizer proper presses the bottom thereof against the inner edge C of the washerC. This is particularly the case when the atomizer has an inclined bottom D', as shown. In this manner an air-tight joint is obtained between the bottom of the atomizer andthe ,washer C, and the ent-ire amount of air expelled by the 7o compression of the bulb A is forced to pass into the air-conveying tube E.

It will vof course be understood that the stopper G is removed when the atomizer is to be used.

When Vit is desired to place the atomizer within the bulb when not in use,r the atomizer is rst unscrewed from the thimble B and then inverted Vand introduced into the thimble in such inverted position.V The diameter 8o of the smooth portion of the atomizer-body D is somewhat'less than that of the threaded portion D2, so that the main portion of the atomizer-body may be slid into the thimble B. The openingfsurrounded by the inner edge C of the washer Cis slightly smaller than the cross-sectionof the main portion of the atomizer-body. VThus in sliding the atomizer-body through the washer into the position shown in Fig. 2 the washer will be 9o slightly distendedand will hug the sides of the atomizer-body with sut'cient friction to prevent' any accidental displacement of the atomizer-body relatively to the bulb; I desire it to be understood that it is not-necessary to screw the atomizerbody into the thimble in the position illustrated by Fig. 2, since the washer C efciently holds the atomizerbody in position. The screw-threaded portion D2 and the bottom D project from the loe thimble B, and thus afford a handle for conveniently withdrawing the atomizer body from the thimble when it is desired to again assemble the parts in the position shown in Fig. l.

Various modifications may be made Without departing from the nature of my invention.

I claiml. The combination with an atomZer-bulb of a thimble arranged at the discharge end of the bulb, a perforated Washer located at the inner portion of the thimble and an atomizerbody adapted for reversible connection With said thim ble, the said Washer being arranged to engage the bottom of the atomiZer-body when the latter is in its extended or operative position, while the said washer engages and friclionally holds the side Wall of the at omizer-body when the latter is inverted to extend through the thimble andthe Washer into the bulb.

2. The combination with an atomiZer-bulb, of a reversible atoxnizer-body arranged to be received within the bulb or to be projected therefrom, and a perforated Washer located at the discharge end of the bulb and arranged to clasp the side wall of the atomizer-body when the latter is Within the bulb, While when the atomizer-body extends outwardly from the bulb, the bottom of such body forms an air-tight joint with said Washer.

3. The combination with an atomiZer-bulb, of a thimble located at the outlet of said bulb and provided with an internal screw-thread, an atomiZer-body, the main portion of which is of sm aller diameter than the innerdiameter of said thimble, said atomizer-body being provided With an inclined bottom, and adjacent thereto, With a screw-thread adapted to t that of the thimble, and a perforated Washer arranged to engage theinclined bottom of the atomizer-body when the latter is projected from the bulb, and to surround and frictionally engage the side wall of the atomiZer-body When the latter is arranged Within the bulb.

In testimony whereof I have hereunto set my hand in the presence of two :subscribing Witnesses.
